Ireland and several other European member states have been identified as the most competitive in the EU in terms of milk production growth since the abolition of milk quotas in 2015. The number of specialist dairy farms in Ireland has remained relatively unchanged over the past decade, and farmer-owned co-ops have a high market share in several countries. The EU dairy production has increased due to the elimination of the milk quota system, but the sector is facing economic, environmental, and social challenges, and environmental concerns are paying an increasing influence on the dairy sector.
